IMPROVEMENT lN ORE SCOURERS. AMALGAMATORS, AND CONCENTRATORS.

Specification forming part ofLctters Patent No. 152,044, dated June 16,1874; application filed April 30, 1874.

fully described and claimed.

Referring to the accompanying drawings forming a part of thisspecification, Figure l is a perspective view of my machine. Fig. 2 is asectional elevation.

A. represents an oscillating concentratingpan, known as the Praterconcentrator, which is ordinarily driven at the rate of about twohundred oscillations per minute; but my rubbing or scouring device canbe combined with any other pattern or style of concentrator having asimilar motion. B is the vertical shaft, about which the pan Aoscillates or partially rotates back and forth with a jigging motion. Inmy device, this jigging motion not only eflects the concentration, asusual, but also provides the desired motion of the rubbing-surfaces. Uis a groove or channel, into which the heavy particles of sulphuret andmetal are concentrated by the action of the pan A, and from which theyare discharged, while the lighter or worthless portions are carried awayby the water over the center discharge of the pan. Outside of thechannel or groove 0 I construct or place an annular die, D, which may bemade in segments to facilitate renewal; and outside of this a channel,E, while the vertical. rim F is outside of the channel E, surroundingthe whole. I thus enlarge the diameter of the pan according to the widthof the die D and channel E. The rubbing-shoes G G can be applied in anyconvenient manner to the upper surface of the die D; and they can be.made in several parts, or in one continuous piece, having openings orslots through which he pulp can pass between the rubbingsnrfaces. In thepresent instance, I have represented a ring, H, corresponding in sizewith the annular die D, and which is attached to the arms I I and a hub,K, which turns freely around the vertical shaft B. This ring may beconstructedso as to form the upper rubbing or scouring surface, ordetachable shoes may be secured to its lower side, so as to bear uponthe annular die D. The number of shoes employed is not material, but asufficient num ber of spaces or slots, 0 0, should be provided to allowthe pulp to pass in between the rubbing-surfaces. This ring will receivea resultant or backward motion from the sudden impulse which it receivesfrom the jigging motion of the pan, so that it slowly rotates, thusrubbing or scouring in a continuous track. To facilitate this motion,the shoes may be constructed with inclined ends. The pulp is fed intothe channel E either through pipes P, from the central hub K in theordinary manner, or in any other convenient way. Now, as soon as thepulp rises in the channel E above the top of the dies D, it will beginto flow over into the channel or groove U through the openings 0 O. Theoscillating or jigging motion of the pan A below the ring of shoes Hwill cause the pulp to be rubbed by the opposing surfaces of the shoesand dies in its passage from one channel to the other, and thus removeany coating which may envelop the particles of metal, and brighten them,so that they will readily amalgamate when brought into contact withquicksilver.

I am aware thata machine has heretofore been constructed combining anamalgamator, concentrator, and scourer, therefore I do not claim thisbroadly; but

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

The pan A, with the rim F, dies D, and outside channel E, in combinationwith the rubbing-ring H, having the slots 0 0, all constructed,arranged, and operated as set forth.

In witness whereof I hereunto set my hand and seal.

WILLIAM H. PATTON.
